Hi Guys, Need some help with a noisy pump. Just got a brand spanking new Mag 5 and it's noisy. It making a clicking sound which I'm thinking might have something to do with the impeller. I opened it up and everything seems to be fine. Any suggestions?

Thats what I've been reading. But what kills me is that I also read posts where people say their Mag5 is quiet but mine is nowhere near that. I wonder if i just have a defective unit and I just need to launch this sucker back.
